  1. 8 de jun. de 2024 · DNA, organic chemical of complex molecular structure found in all prokaryotic and eukaryotic cells. It codes genetic information for the transmission of inherited traits. The structure of DNA was described in 1953, leading to further understanding of DNA replication and hereditary control of cellular activities.

  2. In order to understand the biological function of DNA, you first need to understand its molecular structure. This requires learning the vocabulary for talking about the building blocks of DNA, and how these building blocks are assembled to make DNA molecules.

  3. En este artículo, exploraremos brevemente cómo se descubrió la estructura de doble hélice del ADN con el trabajo de James Watson, Francis Crick, Rosalind Franklin y otros investigadores. Luego revisaremos las propiedades de la doble hélice en sí.

  4. 21 de ene. de 2021 · What is the Structure of DNA? DNA molecules are polymers, which means they are large molecules made up of many smaller molecules. The small molecules that make up DNA are called nucleotides.

    9 de oct. de 2019 · The structure of DNA. In the early 1950s, the identity of genetic material was still a matter of debate. The discovery of the helical structure of double-stranded DNA settled the matter — and...

  6. The basic structure of DNA is a double helix, which consists of two long strands of DNA wrapped around each other. Each strand consists of many nucleotides, each consisting of a sugar and phosphate group, which form the sugar-phosphate backbone of DNA, and a nitrogenous base, which determines the identity of each nucleotide.

    The structure of DNA is dynamic along its length, being capable of coiling into tight loops and other shapes. In all species it is composed of two helical chains, bound to each other by hydrogen bonds. Both chains are coiled around the same axis, and have the same pitch of 34 ångströms (3.4 nm).
